Hi everyone,
I was trying the following definition: a(1) = 1, a(n) is the least positive integer, not already in the sequence, such that for each odd term, k at position m, k+1 must be located at m+k+1. 
a(1) = 1 which means 2 must be located at 1+2 = 3. So, a(3) = 2. 
a(2) = 3 which means 4 must be located at 2+4 = 6. So, a(6) = 4. 
a(4) = 5 which means 6 must be located at 4+6 = 10. So, a(10) = 6. And so on.
I found that the resulted sequence is A115966 (inverse permutation to sequence A094077). Should a comment be added to A115966?
Best,
Ali
